Kotlin roadmap

Welcome to the Kotlin roadmap! Get a sneak peek into the priorities of the JetBrains Team.

Key priorities

The goal of this roadmap is to give you a big picture. Here's a list of our key projects – the most important things we focus on delivering:

K2 compiler: a rewrite of the Kotlin compiler optimized for speed, parallelism, and unification. It will also allow us to introduce many highly-anticipated language features.
K2-based IntelliJ plugin: faster code completion, highlighting, and search, together with more stable code analysis.
Kotlin Multiplatform: streamline build setup and enhance the iOS development experience.
Experience of library authors: a set of documentation and tools helping to set up, develop, and publish Kotlin libraries.
